What C35 Means
C35 is the shorted reading from the relay board thermistor on a Renaissance-series wall oven. The control will not run a cooking mode while the relay board’s temperature reading is implausible.
Common Causes of C35
- Relay board thermistor shorted
- Heat damage on the relay board
🔧 One Safe Check You Can Try
Try one breaker reset. If the code stays, book service; there is no owner-level fix.
⚠ Why You Shouldn't Go Further Than That
- Relay board replacement involves 240-volt element wiring that must go back exactly as it came off.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
